Hello, and thank you for trying to assist. When I registered my domain name, I installed vBulletin, and put the installation into a sub directory: www.mydomain.com/forums I have since switched to XenForo, and installed it in my root directory, however under Admin CP Options Basic Board Information Index Page Route There was an entry of /forums. I don't recall if i entered than upon installation,mor if it was a default option. Regardless, I have since removed this and saved, with no apparent consequences. A sample URL is: http://www.xdebate.com/index.php?forums/xdebate-of-the-week.2/ Now, I deleted the database to my old vBulletin forums, but I never deleted the /forums directory in my website's root directory. Here is my issue: when I check off the "Use Full Friendly URLs" in my Admin CP, it removes the "index.php?" from the URL, making it: http://www.xdebate.com/forums/xdebate-of-the-week.2/ Prior to deleting my old vBulletin forum database, that link brought me to my old vBulletin forum. However, since deleting my old vBulletin database, it produces the following error: There is a serious error and the page cannot be rendered How can I fix this, as I want to utilize the "Use Full Friendly URL" option. Again, thank you for any assistance you may provide.
